ATTU RN EYS L is connected to the top of the said dome by hinges l1, and on the opening of this cover or door, access can be had to the interior of the dome through a doorway l8, normally closed thereby, the cover or door being sealed by a gasket l9, counter-seated in the doorway framing, as best seen in Figure 2 of the drawings, so as to render the interior of the said dome fluid-tight when the machine is operating. The panel 20 of this cover or door is also seal-tight.

At opposite ends of the dome l5 in longitudinal alignment following the central axis of the same are adjustable packing glands 2|, through one of which works a vibrator stem 22, while through the other works a follower stem 4 mounted a vertically swingable spray or let nozzle 55, which is designed to direct cleaning fluid into the bearing 31 when held by the heads 35 and 36, for the cleaning thereof and the nozzle 55 is connected to the arbor by means of a pipe 53. The arbor 53 is turned or moved longitudinally by a hand bar or crank 56 threadably secured thereon and conveniently located and exposed for manual actuation, as best seen in Figures 1, 3 and 14 of the drawings. This arbor 53 also supplies the nozzle 55 with air under pressure from a supply pipe 51, which involves a 23, the former being detachably wedge keyed at 24 to a coupling 25, pivotally connected by a cotter pin 26 to an eccentric strap 21, engaged about an eccentric 28, splined at 29 to a'powershaft 30, of a vibrator motor 3|, of the electric type, and stationarily mounted on a support or shelf 32 built on the tank ID, as best seenin Figures 1 to 4, inclusive of the drawings.

The stem 22 is connected by means. of a pin 33' and a slidable coupling 33. to the gland 2| next thereto, and in this manner is held against rotation. The stem 23 is acted uponby a tensioning spring 34, and both stems at their approaching ends within the dome [5 have separably interfitting substantially cone-shaped and substantially arrow-shaped interchangeable and removable clutching heads 35 and 38 respectively, which in detail are clearly shown in Figures 15 to inclusive, of the drawings for the gripping and holding of a caged bearing 31 as illustrated in Figures 15 to 18 inclusive. The stem 23 at the outer exposed end without the dome ,l'5 is provided with a hand grip or knob 38, so that the heads can be separated from each other to clamp the bearing 31 or unclamp the same, as should be obvious. These heads and 36 when interfitted with each other clamp the bearing for maximum exposure thereof within the dome I5 for cleaning operation of the machine.

The dome i5 is joined with the top of the tank I!) by a fluid discharge throat 39, which serves also as a pedestal and from this throat depends within the tanka discharge tube 43, having the radially spoke-like arranged discharge nipples 4| at the lowermost end thereof and above the bottom of the said tank. Above'the lay of the nipples 41 within the tank in is a reticulated strainer 42, while between the latter and the bottom I I of such tank is a filling of flltering material 43, in which the nipples are embedded.

The tank I0 is provided with a hot air outlet 44, which enters 'the same through the top l4 to one side of such tank, located on the top on the opposite side from the outlet 44 is the cleaning fluid flller inlet 45, and a determined level of the cleaning fluid 45 therein is maintained by a hand-operated valved draw-off cock at the side wall of the tank [0. Extending upwardly and vertically from the tank Ill through the top H thereof is a fluid lift pipe 41, which at the submerged lower end within the fluid is fitted with a return check valve 48, and at the upper end of such pipe above the top I4 of the tank It! is a, union 49, connecting it to a lead having valved couplings 5|, the control valve .being indicated at 52, is connected to .a horizontally disposed tubular turning and. longitudinally slidable feed arbor 53, fltted 'in' packing glands 54, crosswise of the dome .l5- in which is filter 58 for air cleaning purposes to which is connected the air inlet pipe 6|, the filter being fixedly mounted upon the tank 10, as appears in Figure 1. Also the pipe 51 is fitted with a pressure control valve 59, and additionally a cut-off valve Ell, respectively both being hand operated. 1

The valve 59 has an inlet pipe 59 slidably received in the packing gland 56' which is threadably connected to the crank 56. Thus the cavity 51' in the gland 56 intermediate the arbor 53 and pipe 59 permits longitudinal sliding movement of the end of the arbor as desired and a nipple '58 connects the valve 52 to one of the packing glands 54 by means of a sleeve 59' in which the opposite end of the arbor 53 isslidably mounted and a cavity 50' intermediate the arbor 53 and nipple 58 permits longitudinal movement of this end of the arbor as desired.

On a shelf Bi at one side of the tank in exteriorly thereof is demagnetizer 62, having an electric extension cord 63, provided with a separable joint 64, the motor I being also provided with an electric extension cord '65, having a snap cut-off switch 66, and by these cords electric current supply will be had to the respective motor and demagnetizer, as should be apparent on plugging in such cords to the electric current source.

Intercepting the air supply to the filter 5815a spreader 61, which is for spraying the air within the said filter. 1

Projected into the tank [0 from a mounting 68 thereon, is an electric heater 69, whichis well within the filter 43, the. heater being of the electric thermostatic type, and includes the electric extension cord 10, for current supply thereto. The purpose of the heater E9 is to heat the clean ing fiuid from low to various temperatures as desired. I 7

It should be apparent that the used cleaning fluid returns from the dome l5 into the tank In, so that'the same under re-conditioning thereof is used over and over again in the machine and a valve 16 located at the bottom of the tank per-l mits the cleaning fluid to be drawn from the tank when desired.

The bottom ll of the tank is provided with a manhole cover- H, giving access to the filling in the lower portion of such tank I!) and also to,

from the nozzle 16 it is directed on the bearing 31 for the cleaning and drying thereon.

To prepare the machine for operation, the tank I0 is filled up to a determined level with thebest grade of cleaning fluid then air within the tank is exhausted therefrom above such level, and the electric heater 6B is turned on to heat the fluid to approximately 140 degrees upward to 170 degrees F., or medium temperature as desired. To reclaim bearings which have been in use a long time, it is best to wash the bearings in kerosene oil before being put in the reclaiming machine. This helps to remove the hard grease from the bearing. Whereas, in cleaning new bearings, no kerosene oil will be used.

The ball bearing to be cleaned must be demagnetized due to the fact that a ball bearing generates a magnetic field and therefore making the chips, dirt, etc. adhere to the balls inner and outer races. When you demagnetize the ball bearings, the dirt and chips, etc. are freed to come out when placed in the dome I5. A second feature in demagnetizing the ball bearings is that a neutral piece of metal will wear longer than one that is held back by magnetic forces.

I is essential that the tank be filled with the proper oil and that it is thoroughly heated. Thus, the first step in the operation is to place the bearings on the demagnetizer at one side of such bearing and thereafter reverse the bearing on such demagnetizer. The final step is to place the bearing taken from the demagnetizer on the vibrator cone head within the dome [5, then close the door securely, turning on the vibrator mechanism, and effecting a hot spray of oil gas under high pressure through the bearing while vibrating. The gas is now turned off and the bearing is sprayed with air for the drying and spinning thereof. This insures a clean bearing with a light oil film for protection against rust. Thereafter, the vibrator and air are turned ofi and the bearing cleaned is removed from the machine, for further operations of the latter in cleaning placed bearings therein.

It is believed that the operation and construction of the device will be apparent to those skilled in the art and it is to be understood that changes may be made in the details of construction, arrangement and combination of parts, providing they fall within the spirit of the invention and the scope of the appended claims.
